This book constitutesthe proceedings of the 12th International Workshop on Algorithms and Models forthe Web Graph, WAW 2015, held in Eindhoven, The Netherlands, in December 2015. The 15 fullpapers presented in this volume were carefully reviewed and selected from 24submissions. They are organized in topical sections named: properties of largegraph models, dynamic processes on large graphs, and properties of PageRank onlarge graphs.

This book constitutes the refereed proceedings of the 6th International Workshop on Algorithms and Models for the Web-Graph, WAW 2009, held in Barcelona, Spain, in February 2009 - co-located with WSDM 2009, the Second ACM International Conference on Web Search and Data Mining. The 14 revised full papers presented were carefully reviewed and selected from numerous submissions for inclusion in the book. The papers address a wide variety of topics related to the study of the Web-graph such as theoretical and empirical analysis of the Web graph and Web 2.0 graphs, random walks on the Web and Web 2.0 graphs and their applications, and design and performance evaluation of the algorithms for social networks. The workshop papers have been naturally clustered in three topical sections on graph models for complex networks, pagerank and Web graph, and social networks and search.
